A person of weight W is suspended by both hands from a high bar as shown. The center of mass is directly below the bar. (a) Find the horizontal and vertical components Fx and Fy, where F is the force exerted by the bar on each of the two hands. (b) Given the additional information about the arm shown in the second drawing, calculate the components of R, the force exerted by the humerus on the forearm through the elbow, and the tension T in the biceps tendon. Neglect the weight of the arm, and assume that T and R are the only forces exerted on the forearm by the upper arm. 10 R.
